10h

Auto detect flash type to load appropriate flash R/W codes into the

 

run time area in F000 for ESCD & DMI support.

11h

Reserved

12h

Use walking 1’s algorithm to check out interface in CMOS

 

circuitry. Also set real-time clock power status, and then check for

 

override.

13h

Reserved

14h

Program chipset default values into chipset. Chipset default

 

values are MODBINable by OEM customers.

15h

Reserved

16h

Initial Early_Init_Onboard_Generator switch.

17h

Reserved

18h

Detect CPU information including brand, SMI type (Cyrix or

 

Intel) and CPU level (586 or 686).

19h

Reserved

1Ah

Reserved

1Bh

Initial interrupts vector table. If no special specified, all H/W

 

interrupts are directed to SPURIOUS_INT_HDLR & S/W

 

interrupts to SPURIOUS_soft_HDLR.

1Ch

1Dh

Initial EARLY_PM_INIT switch.

1Eh

1Fh

Load keyboard matrix (notebook platform)

20h

21h

HPM initialization (notebook platform)

22h

23h

1. Check validity of RTC value:

 

e.g. a value of 5Ah is an invalid value for RTC minute.

 

2. Load CMOS settings into BIOS stack. If CMOS checksum fails, use default

 

value instead.

 

3. Prepare BIOS resource map for PCI & PnP use. If ESCD is valid, take into

 

consideration of the ESCD’s legacy information.

 

4. Onboard clock generator initialization. Disable respective clock resource to

 

empty PCI & DIMM slots.

 

5. Early PCI initialization:

 

-Enumerate PCI bus number

 

-Assign memory & I/O resource

 

-Search for a valid VGA device & VGA BIOS, and put it

 

into C000:0.

27h

Initialize INT 09 buffer

28h

29h

1. Program CPU internal MTRR (P6 & PII) for 0-640K memory address.

 

2. Initialize the APIC for Pentium class CPU.

 

3. Program early chipset according to CMOS setup. Example: onboard IDE

controller.

4. Measure CPU speed.

5. Invoke video BIOS.
